Most of the work came from making sure that all the luck tests followed Adventurer rules. I did this by looking at the situation that the character was in and finding the appropriate talent to use instead. I then had to convert all of the stat changes to something Adventurer appropriate. I made all the skill changes bonuses or penalties to your Battle Skill in your next combat. I kept all the stamina changes the same and instead of gaining luck points, the hero gains the ability to re-roll failed rolls which they can use during the adventure (but they can't be used afterwards).

The range of levels of the monsters goes from 0 to 10, so you will need to be quite a high level character to complete it. Why don't you try it with a level 5 character or a level 9 character or even a level 13 character? If I had more time, I would modify it so that there would be 4 different versions - one for a level 1-4 character (adventurer), one for a level 5-8 character (champion), one for a level 9-12 character (hero) and one for a level 13-16 character (legend).

However, I hope you enjoy it and that you've enjoyed the other Adventurer goodies that I've made this month.

Edit: At first, I forgot to add what you get when you get the Warlock's treasure, so I have added this to the document.

If you win, you get the following things:

Coins: Gain 1000
coins + your level x100 coins.

Gems: Roll 4 times on treasure table 3 with a +6 bonus to
find out the coins value of all the gems you have found.

Warlock’s spellbook:
Roll 4 times on treasure table 21 to determine 4 spells in the spellbook
that you can learn. You are able to
learn them if you succeed at a Mind (Arcane lore) check with a difficulty equal
to the difficulty of the spell.

You are
also able to avoid any combat with any creature in Firetop Mountain and you may
check what any action leads to as if you had the Divination spell without
making a roll or losing magic points as long as you are in Firetop Mountain.
